Thank you once more Prof. Loeb. This piece you have posted is a beautiful reminder of each spring and Fall: if you want to know what or most dependable reminders of human (nature) phenologies--- observe the plants and animal. My local signs include orb spiders constructing amazing webs at my face-height, mice looking for warmer nesting sites, Canada geese on the move, locust trees and big-leaf maples gaining tinges of bright yellow to come.
